PHP pdo_mysql Extension Installation steps (RPM)

Seeing the cakephp documentation requires you to install the pdo_mysql extension, you try to install it.

My system here is CentOS 6.0. If your system is a different version of Linux/unix, you can refer to it. If your system is windows, sorry, the following is not suitable for you, please go.

The first is to download the pdo_mysql extension of the source package. The download page is here: Http://pecl.php.net/package/PDO_MYSQL. You can download it first and then upload it to the server using FTP.

I was copying it later using wget to download directly to the server side.
# wget Http://pecl.php.net/get/PDO_MYSQL-1.0.2.tgz

Then the decompression.
# TAR-ZXVF Pdo_mysql-1.0.2.tgz

Enter the extracted directory and execute the phpize.
#/usr/local/php/bin/phpize
Configuring for:
PHP Api version:20100412
Zend Module Api no:20100525
Zend Extension Api no:220100525

The following generates makefile. The following two parameters must be added, I did not add at the beginning, the results are not found in the Php-config and MySQL header files.
#./configure–with-php-config=/usr/local/php/bin/php-config–with-pdo-mysql=/usr/local/mysql

Make a soft connection to the header file of MySQL before making it. Because MySQL installs the time to specify the directory, does not make the soft connection, still cannot find the header file.
# ln-s/usr/local/mysql/include/*/usr/local/include/

Then make and make install.
# make
# make Install

You will then be prompted as follows, meaning that the extension is installed in the following directory.
Installing Shared extensions:/usr/local/php/lib/php/extensions/no-debug-zts-20100525/

For convenience, I moved the pdo_mysql.so file to the extensions directory.
# mv/usr/local/php/lib/php/extensions/no-debug-zts-20100525/pdo_mysql.so/usr/local/php/lib/php/extensions/

You can then modify the php.ini file.

Find Extension_dir = "./" This line, remove the comment, and modify the path.
Extension_dir = "/usr/local/php/lib/php/extensions/"
I tested this and found that PHP only looked for extensions from that directory, not subdirectories in that directory. So I moved the so file to this directory for unified management.

Find Extension=php_pdo_mysql.dll this line, remove the comment, and modify the file name later.
Extension=pdo_mysql.so
File name is not the same, the PHP_ prefix is removed, otherwise the file cannot be found. Behind the DLL is the name of the file under Windows, we changed to so.

The final restart of Apache is possible. Use Phpinfo () to see that the discovery has taken effect.
